[avrdude-dev] Programmer Not Responding

[address@hidden]

Hi Everyone,
Well I have a technical problem regarding Avrdude. Need Help

My OS is Ubuntu Lucid Lynx and I have installed avrdude, avrlibc, etc. all
carefully and correctly.
But when I connect Arduino Duemilanove with it and try to upload any program
it says:
*stk500(): Programmer is not responding.*
*
*
In Arduino (ver 0018), I have selected Board correctly, port /ttyUSB0
correctly. And it was working well before.*
*

Can you help me solve this.
Thanks.
